Tallahassee Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Tallahassee's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Tallahassee, FL — 190 swim days a yearThe bar compresses Tallahassee's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 21–March 14 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 14. Wherever the today marker sits, the nearest color change is your next appointment.
The Tallahassee pool calendar
Opening — target February 28
Open by February 28 — a two-week head start on the March 14 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 14
Hold the cover until November 11, then winterize by November 14, a week ahead of the November 21 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Tallahassee's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 53° | 53° | 59° | 65° | 72° | 79° | 82° | 83° | 81° | 75° | 65° | 57° |
Warmest water typically June–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Sunrise's pool season and Tamarac's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.
Tallahassee pool season FAQ
When should I open my pool in Tallahassee, FL?
Open by February 28 — the model places Tallahassee's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Tallahassee opening guide has the 12-step sequence.
When should I close my pool in Tallahassee?
Close by November 14: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Tallahassee closing guide sequences the work backward from that date.
How long is the swim season in Tallahassee?
Tallahassee averages 190 days a year with normal highs of 80°F or better — about 35 days later than the Florida median. The Florida season index ranks all 64 covered cities by the same metric.
How warm does pool water get in Tallahassee?
An unheated pool near Tallahassee typically peaks around 83°F in high summer and bottoms out near 52°F in winter, spending roughly 4 months at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
